A heat pump is a device that transfers heat energy from a source of heat to a destination called a “heat sink”. Heat pumps are designed to move thermal energy in the opposite direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one. A heat pump uses a small amount of external power to accomplish the work of transferring energy from the heat source to the heat sink.

Still, there was one piece of evidence that remained pretty alarming. The island is strewn with sharpened pieces of obsidian, called mata’a, which look alarmingly like spearheads. When Captain Cook came to the island in 1774, members of his expedition reported that the Rapa Nui “had lances or spears made of thin, ill-shaped sticks, and pointed with a sharp triangular piece of black glassy lava.” Given the superabundance of these “spears” all across the island, it seems obvious that a lot of murdering was going on.

Call centers have long sought to analyze customers’ voices for signs of agitation or frustration. Software is getting much better at analyzing social interactions and emotions thanks to clever new machine-learning techniques and copious amounts of training data.

He goes on to argue that AI will continue to develop in siloed form, where new and impressive machines continue to scare doomsayers for their abilities within relatively narrow task domains while remaining “incredibly dumb” when it comes to everything else.

Going forward, developers will be able to respond to customer reviews on the App Store “in a way that is available for all customers to see.” This will allow developers to address negative reviews for the first time ever

In this YouTube channel I publish “creative coding” video tutorials every week. Subjects covered range from the basics of programming languages like JavaScript (with p5.js) and Java (with Processing) to generative algorithms like physics simulation, computer vision, and data visualization.

I’m Daniel Shiffman. I teach at ITP (http://itp.nyu.edu) and help to administer the Processing Foundation (http://processingfoundation…). Here l I publish “creative coding” video tutorials every week. I also answer questions during live streams!
